Thanks to the exploding world of mobile, the computer industry has seen a refreshed interest in high efficiency components. Though Intel has always made a wide range of processors, until lately the company’s low-power products were sometimes seen as second-class citizens of the CPU world. Sure, they used less power, but this was often achieve this with lower clock speeds, fewer features, and sometimes the disabling of cores in the case of multi-core processors. With the Ultrabook initiative Intel has renewed emphasis on efficient processors that are not just on equal footing as the rest of their offerings, but rather showcase the extent of Intel’s processor prowess. The latest Ivy Bridge Core U-series processors found in Ultrabooks are more than just low-power — they are highly efficient processors capable of a high dynamic range of computing tasks. By packing the latest and greatest processor technology into a package that also has practical limits on how much power it can draw and how much heat it can produce, these CPUs present an alternative to using a standard CPU and simply slapping in a big battery; But which is better?

The Samsung Galaxy Nexus was announced last month by Google and Samsung as the first phone to run the latest version of Android, 4.0 AKA Ice Cream Sandwich.

While we knew of the large (4.65″) high resolution (1280×720) Super AMOLED display, the 5MP camera, NFC, Bluetooth 3.0, and most of the other details, Samsung stayed oddly quite about any information regarding the CPU and GPU, giving us nothing more than “1.2GHz dual-core CPU”.

Thanks to the Japanese carrier NTT DoCoMo, the beans have been spilled on the Galaxy Nexus’ CPU. The 1.2GHz dual-core CPU is indeed the Texas Instruments OMAP 4460 platform which also includes the PowerVR SGX540 GPU. TI claims that the PowerVR SGX540 has up to 2x better performance than the previous SGX530 GPU. OMAP 4460 also has support for 1080p encoding (capture) and decoding (playback) at 30 FPS. Samsung’s last Nexus phone, the Nexus S [review], didn’t even record 720p video. This time around, Samsung is taking full advantage of the platform’s capabilities.

Samsung UK has confirmed Galaxy Nexus availability for November 17th, but it seems that retailers aren’t so sure about that. Amazon UK has moved the shipping date for the Galaxy Nexus from the 17th of November back to December 2nd. Amazon UK currently lists the 16GB Samsung Galaxy Nexus unlocked for £519.99, which converts to a pricey $837 USD.

Most phones in the US aren’t bought off-contract, so when it comes to typical US pricing, Android Central has shown what appears to be a leaked Costco inventory screen which prices the Samsung Galaxy Nexus at $289. The phone is expected to be available across both AT&T and Verizon in HSPA+ and LTE flavors, respectively.

The starting point for a mobile internet device design is to look at the processing platforms available in the market. I’ve spent the last few days researching and reviewing the ARM-based CPUs and platforms and put together a full report that you can find over at UMPCPortal.

If you’re tracking news about MID and ‘smart devices’ from CES next week, keep this as a reference.
